Photorealistic diamonds - is it possible?

[leshaaa]

Hi to all!

Is it possible to make photorealistic diamonds in Unity? Ideally I’d like to get quality approximate to:

Hybrid Ray Tracing Real time demo - Rigid Gems 2.0

YEBIS OpenGL ES 3.0 Tech Demo

Is it technically possible and is there any example: video, screenshot, tutorial or paid asset?

The first demo is using a realtime raytracing engine - probably written specifically for that scene. So Unity - no.

But yes it is possible, if you are good with writing shaders. What you need to do is simulate light passing and refracting in the object (for physically accurate results) or you can probably fake it well enough with PBR and some well placed lights.

Korno, thank you for the answer! Unfortunately I have no skills in shaders yet. I have skills only in C#. Is PBR means Physically Based Rendering? Could you advise me some tutorials to learn about shaders or fakes regarding to rendering diamonds?
